So here is the problem. I tend to ride on the outside of my foot, especially on my right. So basically, my foot is tipped to the outside in the stirrup. After riding for a while, especially in 2-point or trying hard to really push my heels down the tendons start they get very sore. If I keep riding and trying to keep my heels down, then it feels really unstable. Today, I took my feet out of the stirrups a couple of times and rolled them around but at one point my ankle gave out and my foot turned in the stirrup and I had to stop.
Obviously I am trying to get myself to not do this. I am trying to balance my foot a little better and it helps to point my toes out a little. But it doesn't seem to be helping. I think that the tendons are a little loose from previous injuries and weak from being off. Any ideas to help this?
